Is 4 wheel buick 45 fin drums enough to stop a 392 hemi powered coupe? some people tell me I'm crazy other people say it will be fine.
Yes ! Condsidering people got 'em stopped with early Ford brakes you should be fine. Once you have enough brake power to lock the wheels more won't help a bit. Now if you plan on going road racing maybe ,just maybe, you could think about front disks.
